Synopsis

WordPress 5.3.x < 5.3.1 Multiple Vulnerabilities

Description

According to its self-reported version number, the detected WordPress application is affected by multiple vulnerabilities :

 - Two cross-site scripting (XSS) vulnerabilities exist due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit these, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session.

 - A remote, authenticated, unprivileged user can make a post sticky via the REST API.

 - wp_kses_bad_protcol() has been hardened to ensure that it is aware of the named colon attribute.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update to WordPress version 5.3.1 or latest.
